Abstract: Systems and techniques are provided for path tracing. For example, a process can include establishing a path tracing session associated with path tracing (PT) probe packets from a PT source node of an IPv6 network fabric. A PT probe packet can be received with a first IPv6 Destination Options Header with Path Tracing Option (DOH-PT) header that encodes path tracing information of the PT source node and indicates respective path tracing information for each PT midpoint node along a path from the PT source node to a PT sink node of the IPv6 network fabric. The received PT probe packet can be updated to include a second DOH-PT header that encodes path tracing information of the PT sink node. An updated PT probe packet includes the first and second DOH-PT headers and can be encapsulated with an additional IPv6 header corresponding to forwarding information of a collector node.

Abstract: Systems and methods described herein for storing primitive data for ray tracing and/or rasterization. The data is encoded efficiently into arrays of fixed-size data blocks using a data format which can be directly consumed for ray traversal or rasterization. Vertex data in a block is pre-quantized and stored using a fixed-bit quantization grid. Mesh connectivity is encoded using a triangle strips based on control values representing triangle interconnectivity, and a compressed index buffer storing indices for vertices in each strip. Further, triangle identifiers are derived from the triangle's position in the strip. The block can further store geometry identifiers and opacity maps corresponding to primitive data.

Abstract: Systems and methods for ray intersection against primitives are described. Primitive data is encoded efficiently into arrays of fixed-size data blocks using a data format which can be directly consumed for ray traversal. Vertex data in a block is pre-quantized and stored using a fixed-bit quantization grid. Mesh connectivity is encoded using a triangle strips based on control values representing triangle interconnectivity, and a compressed index buffer storing indices for vertices in each strip. Primitives can alternatively be quantized to generate primitive packets, that are stored compactly in, with, or near a leaf node of an acceleration structure. Low-precision intersection testers test a ray simultaneously against primitives to find candidate triangles that require full-precision intersection. Primitives that generate an inconclusive result during low-precision testing are retested using full-precision testers to definitively determine ray-triangle hits or misses.

Abstract: This disclosure presents methods and systems of controlling a counter flow double pipe heat exchanger (DPHE) that includes a hot fluid pipe and a cold fluid pipe. In a method, a temperature error between a reference temperature and a temperature at an outlet of the hot fluid pipe of the counter flow DPHE is determined. A cold fluid mass flow rate is determined from an output of a proportional-integral-derivative (PID) controller based on the temperature error being input to the PID controller. The cold fluid mass flow rate is used for a cold fluid in the cold fluid pipe of the counter flow DPHE. The temperature error is controlled within a predefined range by utilizing parameters of the PID controller that are set by using a harmony search algorithm (HSA) to obtain a minimization of a cost function.
